The reason behind this is the wider groove design allows higher lofted wedges (56-60-degree) to grab the ball to impart more spin, and make spin performance more consistent throughout the wedge set.

The new grooves are combined with Variable Face Roughness (VFR), a face milling technology that maximises both RA (average roughness) and RY (max peak-to-peak depth) to the USGA limit, delivering more control and precision on greenside shots.
